“We had San Francisco Metal Roofing install a new metal roof on our brick apartment building, and the difference is night and day. The crew of four knocked it out in about a week, and they even swept the sidewalk and hauled away every scrap. The building looks sharper than it has in decades.”

“Our Victorian had a tired copper roof that we were honestly scared to touch. They came out, walked us through the whole copper replacement, and matched the original detailing beautifully. It wasn't cheap, but watching that new copper go up was worth every penny.”

“Had them put a corrugated metal roof on our forest cabin and it turned out rock solid. The panels handle the rain and pine needles way better than the old shingles ever did. Took them two days and they left the site cleaner than they found it.”

“Full metal roof replacement on our house, and I was bracing for weeks of chaos. They finished in four days, kept the yard tidy, and the new standing panels look fantastic. Only tiny gripe is they showed up a little later than promised on day one, but honestly the work speaks for itself.”

“We had a leak right around the chimney and couldn't figure out where it was coming from. They got up there, found the failing flashing, and had it sealed and repaired the same visit. No more drips after the next big storm, which is all I wanted.”

“Didn't want the mess of tearing off our old shingles, so we went with the retrofit over them. The crew was in and out in three days and you'd never know there were shingles underneath. Really relieved we didn't have to deal with a full tear-off.”

“Went with standing seam for our place and I'm genuinely impressed with the craftsmanship. The seams are dead straight and the whole roof looks like it belongs on a much fancier house. They cleaned up so well that my neighbor asked who did the work.”

“I was worried about branches hanging over the house and how the roof was holding up, so I booked an inspection. They checked everything, cleared the debris off the panels, and gave me a straight answer instead of a sales pitch. Appreciated the honesty, though I wish they'd had more availability sooner.”
